HARVESTING-MACHINE.

To all whom it may concern:

Be it known that I, DAVIS W. ENTRIKIN, of Kennett Square, in the county of Chester and State of Pennsylvania, have invented certain new and useful Improvements in Harvesting-Machines, of which the following is a specification.

This invention relates to that class of harvesting-machines wherein the out grain is received upon a moving endless apron, and is thereby conveyed sidewise across the machine and delivered to the elevator, which discharges it in suitable condition to be bound either by hand or automatically.

The objects of my improvements are to provide means to advance light or tangled grain that mayfall upon the conveyer, or bringitinto closer contact than heretofore with said conveyer, so that the latter will carry it steadily to the mouth of ,the elevator, as a great difficulty is often experienced with curly or flossy light grain that has not sufiicient weight in it to press enough on the conveyer to be moved thereby, (as there is always some slight resistance caused by the stalks of said grain resting on the cutter-bar or the side of the conveyerframe,) and other means are required besides the moving conveyer to cause it to reach the elevator.

Heretofore reciprocating rack bars placed in the rear of the cutter-bar to advance the butts of grain, as well as rakes and other similar devices pivoted to either side or to the rear of the frame of harvesters, have been used in connection with a stationary platform; but their operation is often objectionable, and that class of harvesters differs materially from those provided with endless aprons. Good results are obtained with the latter class of harvesters upon curly light grain by means of a device or moving lever nearly similar to the one shown in myPatent No. 247,182, of September 20,1881; but while that device straightens the grain just before entering the elevator, in my last improvement the moving lever is made to oscillate over the conveyor in the same direction with its path, and consequently at about a right angle with the lever in said patent. I attain these objects by the mechanism illustrated in the accompanying drawings, in which Figure 1 represents a perspective of a harvesterframe to the rear beam of which my in provcment is attached. Fig. 2 is a perspective view of a similar frame with the improved device secured to the drivers foot-board. Figs. 3 and 4- represent respectively a side view of the upper portion and a perspective of the lower portion of the grain-moving lever.

In said drawings, A represents the front or finger bar of the machine, and A the rear beam. At the inner end of the machine the elevatorframe A is placed, to carry, as usual, the pairs of rolls 1) and 0, around which are 'stretched the elevatingaprons B and O; and the horizontal conveyor D is also mounted upon rolls d, to which motion can be given in any convenient manner.

E represents the dividing-board, and F the drivers foot-board, upon the rear end of which the drivers seat is generally placed.

The above-mentioned parts are in common use; but the means to advance 'flossy light grain, consisting mainly in a slotted lever, I, connected with the frame and adapted to oscill'ate in a plane corresponding with the path of the conveyor, are brought into action as follows, as represented in Fig. 1:

Upon the rear beam, A, of the harvesterframe is adjustably secured a post, J having a horizontal arm, J carrying at its extremity the standard J. This standard has on one side of its upper end a projection, J, made to extend over the pulley or crank wheel K, that gives motion to the lever I. The upper end of this lever is retained connected to the projection J of the standard by a washer placed under the head of the screwj, passing through a longitudinal slot in the lever and screwed into or bolted to the projection J of the standard. The pulley or crank wheel K is pivoted to the standard, andcarries a headed crank-pin, k, that passes through the lever I and (in connection with the screwj in the slot i) causes the lower end to describe a long flat curve over and among the grain that may be upon the conveyor. Motion to the crank-wheel K can be given by connecting the pulley To upon its shaft with a pulley, 0, upon the end of one of the rollers carrying the conveyor-aprons.

In Fig. 2 the lever I and its standard J are shown as connected with the drivers footboard F by means of a horizontal arm, J Said arm may be pivoted to said foot board upon the vertical shaft m, so as to adjust the 2 esaoss path of the lower end of the lever I as may be desired, according to the length of the grainstraw, and then be secured by a locking-pin, on, passing through the arm J and foot-board F, the shaft m carrying two guide-pulleys, n n. Motion can be transmitted to the pulley K from the pulley L on the reel-shaft l; but other wellknown means may be used for opera-ting the arm I, so that it will partly advance or press the grain upon the conveyer.

In Fig. 1 there is shown an arm suspended from the top of the drivers foot-board; but it forms no part of this invention.

To render the lever I more yielding, I prefer to connect it with the crank-pin 7c of the crank or pulley K by passing said pin through a yielding bearing, 19, sustained by springs q in the lower slot, 41 of said lever; and to cause the lower end of the lever I to come at each rotation in contact with a larger amount of grain upon the conveyer I provide said lever with a shoe, I pivoted thereto and adapted to yield by means of flat springs 'i, and thus conform its path more closely to the plane surface of the conveyer.

Having now fully described my invention, what I claim is-- 1. The combination of the frame and movable conveyer of a harvester with a movable arm or slotted lever suspended over said con- 0 veyer, and operating mechanism to cause it to advance or press the grain upon said conveyer in the direction of the path of the latter, substantially as and for the purpose described.

2. The combination of the conveyer, the ele- 5 vator, the foot-board of a harvester, and the horizontal arm J with a standard upon the end of said arm, a pulley provided with a crankpin, and a slotted lever adapted to sweep over the conveyer in the direction of the path of the latter, substantially as and for the purpose described.

3. The combination of the frame and conveyer of a harvester with a slotted lever provided with a yielding bearing, p, a crank, and

operating mechanism, substantially as and for the purpose described. a

4. The combination of the frame and conveyer of a harvester with a crank, a slotted lever adapted to swing over said conveyer, and a shoe, I, pivoted to the lower end of said lever, substantially as and for the purpose described.
